Abstract

The holding hoop for welding flange is one special device for installation of metal pipeline. Technologically, the holding hoop consists of two semi-circular hoops hinged together, and there are one screw and one nut in the other end of the first semi-circular hoop, one connecting seat in the other end of the second semi-circular hoop, three magnetic platforms separated by 120 deg and notches between each two platforms for spot welding. The holding hoop can raise flange welding speed and quality, and may be used in welding flange and pipes.

Description

Clamp special for welding flange
Technical field
The invention belongs to metallic conduit the isolated plant technical field is installed.
Technical background
Along with development and national economy is more and more faster, country is more and more higher to engineering construction construction demand, and especially the requirement to pipeline construction is also more and more higher in the engineering construction, gets twice the result with half the effort, the high-quality and high-efficiency urgent hope of each unit in charge of construction especially.Installation requirement based on various pipelines control gate valves during especially metallic conduit is constructed in the present construction is also more and more higher.Installation control gate valve is the key technology in pipelayer's journey on the metallic conduit, and the control gate valve is connected and fixed by ring flange and pipeline, and this just requires the welding precision height of ring flange and metallic conduit, and welding quality is good, also wants speed of welding fast simultaneously.This solder technology is still continued to use artificial set square localization method now, and welding precision can't accurately be controlled, and weld interval is long, inefficiency, and this has restricted the precision and the process of metallic conduit construction greatly.
Summary of the invention
The purpose of this invention is to provide a kind of clamp special for welding flange, precision height during welded flange on metallic conduit, speed is fast, and welding quality is good.
The present invention is achieved in that clamp special for welding flange, forms circular clip by two semicircle clips, and a side of the first semicircle clip 12 and the second semicircle clip 7 links together by hinge 6; The opposite side correspondence that the opposite side of the first semicircle clip 12 is equipped with moving screw 9 nuts 10, the second semicircle clips 7 is equipped with Connection Block 8;
The interval evenly is provided with three magnetic recording level platforms 2 for 120 ° outside the upper end of the circular clip that two semicircle clips are formed, in the shell of magnetic recording level platform 2, be fixed with magnet piece 11, be fixed with bolt 5 in magnetic recording level platform 2 outsides, on bolt 5, be set with the pressing plate 3 of regulating mounting flange, on pressing plate 3 outside bolts 5, wing nut 4 be installed; Between per two magnetic recording level platforms 2, be provided with spill point weld bond 1.
The present invention can also be at dolioform some welding hole 18 of the middle part of the first semicircle clip 12 and the second semicircle clip 7 processing, can use during with the transition joint of diameter pipeline two of welding like this.
Compare with existing artificial set square fixed-position welding method, use clamp special for welding flange welding precision height, speed is fast, and welding quality is good, and the welder is simple to operate easy to carry, has reduced workman's operation easier and labour intensity.
The scope of application is wide, can be on pipeline welding flange use, also can use with the transition joint of diameter pipeline two of welding; Can use at work high above the ground, Ground Operation.
Product structure of the present invention is simple, and handling ease is with low cost, applies easily, especially requires quality height, the more apparent advantage of engineering that quantities is big at pipeline construction technology.

Fig. 1 is the structural representation of clamp special for welding flange of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the user mode reference diagram of welding flange on pipeline;
Fig. 4 welds two with diameter pipeline transition joint user mode reference diagram.
The specific embodiment
Clamp special for welding flange of the present invention is applicable to seamless pipe, use when metallic conduits such as plating pipe, welded tube weld with the metal flange dish, uses in the time of can also welding the metallic conduit of two identical calibers.
As shown in Figure 1 and Figure 2, a side of the first semicircle clip 12 and the second semicircle clip 7 links together by hinge 6; Opposite side is connected and installed by moving screw 9 nuts 10 and Connection Block 8, makes clip form annular, so that metallic conduit is fixing tight during operation.
The outside, upper end of the circular clip of forming at two semicircle clips at interval 120 ° evenly be provided with three magnetic recording level platforms 2, in the shell of magnetic recording level platform 2, be fixed with magnet piece 11, so that with ring flange adhesive to be welded fixedly on the magnetic recording level platform.Be fixed with bolt 5 in magnetic recording level platform 2 outsides, on bolt 5, be set with the pressing plate 3 of regulating mounting flange, on pressing plate 3 outside bolts 5, the radial position of wing nut 4 in order to fixed flange is installed.Between per two magnetic recording level platforms 2, be provided with spill point weld bond 1, operate when being used for spot welding.
As shown in Figure 3, when metallic conduit 15 and 13 welding operations of metal flange dish, earlier metal tube is trimmed mouth, accomplish fluently the slope, flange is welded clip be stuck in metal mouth of pipe place, again ring flange is placed on the magnetic recording level platform 2 of 120 ° of angles of three one-tenth, magnetic recording level platform 2 holds metal flange by magnet piece 11, again with the pressing plate 3 in magnetic recording level platform 2 outsides and the position while welding between wing nut 4 adjustment flanges and tube wall, adjust behind the weld seam by tightening wing nut 4 clam members 3, simultaneously moving screw 9 is installed in and connects 8, the first semicircle clip 12 and the second semicircle clip 7 are fixedly clamped with metallic conduit by nut 10.
Between per two magnetic recording level platforms 2, be provided with spill point weld bond 1,, form weld seam 14 respectively in 1 spot welding of three some weld bonds, unclamp wing nut 4 after the spot welding firmly and unclamp pressing plate 3, and lemon opens nut 10, moving screw 9 is thrown off from Connection Block 8, unload lower catch hoop, proceed welding again and get final product.
As shown in Figure 4, be processed with dolioform some welding hole 18 at the middle part of the first semicircle clip 12 and the second semicircle clip 7.During the metallic conduit of two identical calibers of welding, metallic conduit 15 and another root metal tube 16 usefulness clips are clamped, seam 17 is stayed the centre position of dolioform some welding hole 18, behind two spot welding stomions weldering location, shed clip, continue again seam crossing is welded.Do not use magnetic recording level platform 2 and pressing plate 3 during operation.
Clamp special for welding flange of the present invention can be designed to series of products, is fit to use with the metallic conduit and the ring flange welding of various calibers, as: DN65, DN100, DN150, DN200 model metallic conduit.
